Here are Sydney / Australia platforms that match brands with pre‑vetted UGC creators (quick summary + what they do):

• Creator Flow — Sydney‑headquartered UGC marketplace that connects brands to a vetted network of Australian creators for fast, scalable UGC video production. (roar.global)

• TRIBE — Australian creator marketplace (founded in Australia) that matches brands with an opt‑in community of creators for branded content/UGC; has a Sydney presence. (tribegroup.co)

• Influee — UGC marketplace operating in Australia that promotes a vetted creator pool (creator academy / screening) for on‑demand UGC video assets. (influee.co)

• Social Shake — Platform/UGC agency that sources creators for brands (claims creator approval and a large creator network for UGC and influencer campaigns). (social-shake.com)

• RMK Creators (RMK Management) — Sydney‑based talent/creator management arm that connects brands with managed creators and production talent for branded content and UGC. (rmk.com.au)

• Vloggi — Sydney software/platform for collecting, standardising and licensing user‑submitted video (useful if you want UGC collection + rights management rather than a creator marketplace). (vloggiapp.com)

Notes:

• “Vetted” processes vary: some marketplaces run formal screening and training (e.g., Influee, Creator Flow), others use opt‑in/managed rosters or agency vetting—check each provider’s acceptance and quality controls before committing. (influee.co)
• If you want, I can narrow this to platforms optimized for: quick ad‑style UGC, enterprise budgets, Shopify/e‑commerce brands, or creators in a specific niche (beauty, fitness, tech) and pull pricing/turnaround details.
